THIS HAPPENED WHEN I WAS CHECKING A CHALLENGE ON A NEW DEV ORG SPECIFICALLY CREATED (NEW) FOR THIS:

Challenge Not yet complete... here's what's wrong: 
There was an unexpected error while verifying this challenge. Usually this is due to some pre-existing configuration or code in the challenge Org. We recommend using a new Developer Edition (DE) to check this challenge. If you're using a new DE and seeing this error, please post to the developer forums and reference error id: DRDIJEQN / SKIYWUOG / JLKPKFPD ...


 

I have read through multiple threads of people suffering from similar problems but cannot seem to find a solution. I have followed the instructions to the letter, read through the advice of some of the contributors on this forum, and have still not been able to get the program to accept the challenge. Regardless of what steps I take which has included deleting and restarting the Residential Opportunities section from scratch, I continually get the same message, "Unwanted fields are still present in the 'Residential Opportunity Page' layout." 

Is there any solution to this problem? 

Thank you,

Jeremy

Can anyone help me on this  ?

Hi,
the challenge is as follows :

Create a camping component that contains a campingHeader and a campingList component.
1.The campingList component contains an ordered list of camping supplies that include Bug Spray, Bear Repellant, and Goat Food.
2.The campingHeader component contains an H1 heading style with a font size of 18 points and displays 'Camping List'.

so i made a lightening application named "camping.app" having code :

<aura:application >
    <br/><br/><br/>
    <c:campingHeader/>
    <c:campingList/>  
</aura:application>


where lightening component "campingHeader.cmp" having code :

<aura:component >
    <h1> Camping List </h1>
</aura:component>

for I have "campingHeader.css" having code :
.THIS {
}

h1.THIS {
    font-size: 18px;
}

and lightening component "campingList.cmp" having code :

<aura:component >
    <ol>
       <li>Bug Spray</li>
       <li>Bear Repellant</li>
       <li>Goat Food</li>      
    </ol>
</aura:component>

when i preview the application it is working nice; but when checking the challenge it says :
"Challenge Not yet complete... here's what's wrong: 
The 'camping' Lightning Component does not include either the campingHeader or campingList component."

please help me know where I m doing wrong. Thanx waiting for your reply

The campingList JavaScript controller isn't setting the 'item' as a parameter or saving the record correctly.

My code is as follows:

    <aura:attribute name="newItem" type="Camping_Item__c"
     default="{ 'sobjectType': 'Camping_Item__c',
                    'Name': '',
                    'Quantity__c': 0,
                    'Price__c': 0,
                    'Packed__c': false }"/>

Working on TrailHead Challenge... (https://developer.salesforce.com/trailhead/force_com_introduction/data_security/data_security_sharing_rules)

Tasks completed:
The custom object must be named 'Project' with a resulting API name of 'Project__c'.   Done
The Name field for 'Project' must be of type Text (not Auto-Number).  Done
The custom object 'Project' must have a custom field of type picklist named 'Priority' with a resulting API name of 'Priority__c'. Done
The role label should be 'Training Coordinator' with the resulting 'Role Name' of 'Training_Coordinator'. Note that you may already have this role in your role hierarchy from a previously attempted challenge.   Done
Set the organization wide settings to public read only.    Done

Here is where I think is the problem:
The sharing rule can be named anything.  
 Create sharing rule under "Sharing Settings" under Project Sharing Rules..  Create a criteria based project sharing rule with Priority custom field equal to High.  Shared with role "Training Coordinator" as read-only access.


What am I missing?
